The files found here are from this source:

Transfer equipment is slightly different though, so it's:

=============================================================================
Tascam DA-20 mkII > Hosa Coax (1meter) > Midiman Delta DIO 2496 [s/pdif] > 
Soundforge 4.5 [record] > CD Wave [cut to preferred samples] > PCM .wav files
=============================================================================

Files:
1. 48khz.wav - this is a 2:39 portion of the beginning of "It's up to you"
1. 44.1khz.wav - same portion as above, but run through a resample process in 
  SF 4.5 at an interpolation accuracy of 4, and applying an anti-alias filter.

2. 48khz.wav - this is a 4:47 portion of the middle of "Tongue 'n Groove"
2. 44.1khz.wav - same portion of T'n'G, same resample process.

Notes:
Fades applied to the first and last 2 seconds of all 4 files using SF for ease on your
ears when doing this... :)

For playback, ssamadhi97 recommends that we use pcabx which can be found at:

Feel free to comment. I'm interested if anyone else thinks there's a difference.
